Exchange Server: How to fix Outlook Web App Security Warning

The Client Access Servers are configured to use Secure HTTP (HTTPS) for Outlook Web App; it is a default setting. If you install the Exchange Server 2010, as self-signed security certificate will be automatically issued for the Client Access Server. As this default certificate is not issued by a trusted certificate authority, users can see a warning when they access OWA stating that there is a problem with the Web site’s security certificate.
It is required to click Continue To This Website at the warning prompt to access the Outlook Web App. Of course, this warning can be disconcerting to the user and have users click to continue anyway sets a bad precedent, training users to ignore online security warnings.

Until you install a certificate from a trusted source on the server, the warning will be continuous displayed to the users.
